Never leave a thermometer inside an oven, grill, smoker, or microwave while cooking unless it is specifically designed for this.
Don’t leave your thermometer on the grill hood or close to an open flame.
When checking temperatures above a grill or fire, be careful that the thermometer body does not get too hot.
Some probes are designed to be left inside an oven or grill, but the thermometer housing itself (where the electronic components are kept) typically needs to be kept cool and should only be brought near heat for short periods.
Since flare-ups temperature can be over 537°C which will damage the probe. To avoid damage, please keep probe and cable away from flare-ups, grill lids, grill grates or other hot spots with high temperatures over 250°C.
